Unity2D屏幕适配方案

看了cnblogs里的一篇文章，终于理解了Unity2D的摄像机系统：http://www.cnblogs.com/flyFreeZn/p/4073655.html

我根据他的方案，改写了两种适配方案：fixedWidth和fixedHeight，就是锁定其中一个变量来适配屏幕。

 using UnityEngine;
 using System.Collections;

 public class GameCamera : MonoBehaviour {
     public string scaleMode = "fixedWidth";

     public float designWidth = 9.6f;
     public float designHeight = 16f;

     // Use this for initialization
     void Start () {
         float aspectRatio = Screen.width * 1.0f / Screen.height;
         float orthographicSize = ;

         switch (scaleMode) {
         case "fixedWidth":
             orthographicSize = designWidth / ( * aspectRatio);
             break;
         case "fixedHeight":
             orthographicSize = designHeight / ;
             break;
         }

         this.GetComponent<Camera>().orthographicSize = orthographicSize;
         Debug.Log (orthographicSize);
     }

     // Update is called once per frame
     void Update () {

     }
 }

你可以修改设计尺寸，记住设计尺寸是通过1:100比例缩放后的。
